    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first wireless communication device may receive a configuration associated with reporting delta channel state information (CSI). The first wireless communication device may compute the delta CSI based at least in part on the configuration, the delta CSI indicating a difference between first CSI associated with a first connection and second CSI associated with a second connection, the first connection being between the first wireless communication device and a base station and the second connection being between the first wireless communication device and a second wireless communication device. The first wireless communication device may transmit, based at least in part on the configuration, a CSI report including an indication of the delta CSI and at least one of an indication of the first CSI or an indication of the second CSI. Numerous other aspects are described.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a radar device may process a transmitted radar signal and a received radar signal to obtain at least one energy level measurement. The radar device may determine that the at least one energy level measurement satisfies a threshold value. The radar device may perform a listen before talk procedure based at least in part on determining that the at least one energy level measurement satisfies the threshold value. Numerous other aspects are provided.

    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may indicate timing alignment factors in support of timing alignment adjustments by a base station or one or more transmission reception points (TRPs). Such timing adjustments may be in the context of cooperative beamforming and may relate to the timing with which the TRPs transmit respective instances of downlink transmissions to the UE. In some cases, the UE may report absolute timing alignment factors to support such timing alignment adjustments. Additionally or alternatively, the UE may report relative timing alignment factors, for example compared to signals received from a reference TRP, to support such timing alignment adjustments.
